Application led. March 23, i918. Serial No. 224,296.

To all @1J/tom?? may concern:

.he it known that l, Beam S'reszxo, a suhiecto the Emperor ot Austria,resident et Hateld, county of Hampshire, and State of Massachusetts,have invented certain new and useful improvements in Snow-Hows, of whichthe following is a specification, y

This invention relates to improvements in attachments to vehicleswhereby snow and the like may be cleared from the path of travel.

The principal object of the invention is to provide' an attachmentrwhich may "ne readily engaged or disengaged from a vehicle,particularly oi the automobile type, and provided with running boards,without material cha-nge in the vehicle or the parts thereof.

These and other like objects are attained hy the 'nevel construction andcombination of parts hereinafter described and shown in the accompanyingdrawings, forming a material part ci this. disclosure, and in whichFigure l is a fragmentary top plan View The snow plow attachments, twoof which are used, one upon each side of the vehicle, are composed ofcurved rigid shear plates 15, arranged diagonally with respect to thecenter line of the vehicle, the lower edges extendingoutwardlysubstantially level with the road over which the vehicle passes.

These shear plates have rigidly secured to them bars l7, formed with andextending singularly from lever arms 18, forked at their opposite ends,the arms 19 'of the forks,

being hingedly engaged by pins 20, with the extending heads 21, formedwith Vdepending lugs 23,Y of brackets 24:, having a level upper surfaceadapted to be tightly engaged with the lower side of the runring hoardl2, the

extreme frontend of the bracket plates 24, terminating in narrowlprojections 25. l

lhe eyes of tension springs 26, engage in the lugs 25 and have theirlower bent ends 60 engaged m corresponding eyes 27, formedwith the outerends of the lever arms 18.

Formed through the running boards are two round openin s receptive ofthe heads 3U of studs rigid y engaged in the ixed 65 brackets 2d, thestuds having recesses 31, v formedupon opposite sides, the samebeing ofconsiderable magnitude and tted to engageuwithin slots 33 extending fromcircular openings 34, formed in sliding plates 35, mounted on the uppersurface of the running boa-rdsfand provided with operating handles 36,by means-otwhich they may be con yeniently operated.'

in order to hold the brackets 24 and the 75 lags 25, in rigidrelationwith the running boards L?, there are formed through the" runningboardsa pair of spaced clrcular openingsl 38, engageable with which arepins 39 provided with collars 40, adapted to rest 80 vupon the surfacesof the lock plates 35, when engaged with either of the openings 38, and'sgireveited against loss by'chains 4l or the ln operation, when it isdesired to attach the snow'plow, the brackets 24 are disposed below therunning4 boards so as to permit the studs 30, to be passed upwardlytherethrough, whereupon they are engaged with the openings 34 in thelock plates 35, the 90 plates drawn length-wisey so as tovcause the.slots 33 to engage with the recesses 3l, of

the studs and the pinsB-l dropped into position, through one of theopenings 38 in the running boards, thus locking the brackets againstmovement. y Y

When it is desired to disengage the snow plow, the pins 39 are raised,the lock plates 35 moved length-wise to permit the studs 30 to passthrough the openings 3d, completely 100 releasing the brackets so thatthey may be stored in any convenient place for further use. A

From the foregoing, talren into'connection with the drawings, a fulldisclosure of the invention has been made and it will be obvious thatthe attachments, can be readily applied and efciently used at anydesired time. Having thus described my invention. what l claim as newand desire to secure by Letters Patent, is.
